Abstract
The utility model discloses an airplane main oil tank oil drainage tool, which comprises a standard configuration oil drainage tool head of a current airplane, a tube joint and a flexible tube joint. The tube joint is provided with a valve, the flexible tube joint is connected to one end of the tube joint, a joint is processed at an oil outlet end of the oil drainage tool head, and the joint is connected to the other end of the tube joint. The airplane main oil tank oil drainage tool has the advantages of simple structure and convenient utilization.
Description
Technical field
The utility model relates to a kind of aircraft main oil tank drain oil unit.
Background technology
The method of draining the oil about the aircraft main oil tank all has specific (special) requirements, such as according to the requirement of Boeing handbook, drains the oil and must adopt the oil-out way of pressure, has 4 kinds of different ways:
1. work simultaneously by fuel charger in the fuel tank and the oil well pump on the oil pumping vehicle and drain the oil, can emit the oil of all fuel tanks simultaneously, this also is the fastest way.
2. only drain the oil with the fuel charger in the fuel tank.
3. only with the oil pumping of the oil well pump on the oil pumping vehicle, the method is very slow.
4. drain the oil by external control devices, need special fastening.
In addition, can also emit fuel oil in the fuel tank at the fuel oil sample point.
For main oil tank, directly withstand the valve of oil drain hole with drain oil unit, fuel oil just can flow out.But the flow of fuel oil is uncontrollable.
Its ubiquitous problem is:
Above several ways, pressure oil pumping all needs oil pumping vehicle to finish.And maintenance and repair generally can not be equipped with oil pumping vehicle, if desired, must coordinate external door (aviation fuel company), program more complicated and spend high.
Gravity is drained the oil also has flow wayward, shortcomings such as the easy fatigue of worker.
Summary of the invention
Therefore, the utility model provides a kind of simple in structure at the above-mentioned defective of present aircraft main oil tank drain oil unit, but aircraft main oil tank drain oil unit easy to use.
The technical solution adopted in the utility model is:
The utility model aircraft main oil tank drain oil unit, the drain oil unit head that comprises current aircraft standard configuration, the hose coupling that also comprises adaptor union and be connected this adaptor union one end with valve, the oil outlet end of described drain oil unit head is processed with joint, and this joint is connected in the other end of described adaptor union.
Aircraft main oil tank drain oil unit according to technical solutions of the utility model has only used three members, only the drain oil unit head of standard configuration has been processed a joint, is equipped with flexible pipe again and just can have drained the oil work, and cost is low.The drain oil unit of at first this structure satisfies on the standard desired pressure drains the oil, and the more important thing is that this drain oil unit can satisfy draining the oil under the various conditions, does not need to coordinate other departments.In addition, this drain oil unit is simple in structure, portable convenience.Have valve in addition, after the oily instrument of Sheng has been expired, can shut valve, change and contain oily instrument, easy to use.
Above-mentioned aircraft main oil tank drain oil unit, described valve is the ball valve valve.
Description of drawings
Fig. 1 is a kind of aircraft main oil tank drain oil unit according to technical solutions of the utility model
Among the figure: 1, drain oil unit head, 2, joint, 3, valve, 4, adaptor union, 5, hose coupling.
The specific embodiment
With reference to explanation accompanying drawing 1, it shows a kind of aircraft main oil tank drain oil unit, the drain oil unit head 1 that comprises current aircraft standard configuration, also comprise adaptor union 4 with valve 3 and the hose coupling 5 that is connected this adaptor union one end, the oil outlet end of described drain oil unit head is processed with joint 2, and this joint is connected in the other end of described adaptor union.
Further, described valve is the ball valve valve, and is simple in structure, good seal performance.
Claims (2)
1. aircraft main oil tank drain oil unit, the drain oil unit head (1) that comprises current aircraft standard configuration, it is characterized in that: also comprise the have valve adaptor union (4) of (3) and the hose coupling (5) that is connected this adaptor union one end, the oil outlet end of described drain oil unit head is processed with joint (2), and this joint is connected in the other end of described adaptor union.
2. aircraft main oil tank drain oil unit according to claim 1 is characterized in that: described valve is the ball valve valve.
